Oscillator, Solo and Compressor

Oscillator​

ASP4816-SE oscillator and master solo controls

The built-in oscillator provides reference tones for system alignment and signal-path checking.

ControlFunction
FrequencySelects 40 Hz, 1 kHz, 10 kHz or 15 kHz
BUSRoutes the oscillator to record buses 1–16
MIXRoutes the oscillator to the stereo Mix bus
LEVELAdjusts oscillator level
ONEnables the oscillator
caution

Ensure the oscillator is switched OFF during normal operation.

Solo​

  • PFL — Pre-Fade Listen: auditions the pre-fader signal.
  • AFL — After-Fade Listen: auditions the post-fader, post-pan signal.
  • SOLO IN FRONT: adjusts the balance between the solo signal and the stereo mix.
  • SIP — Solo in Place: places the post-pan signal from the soloed channel(s) onto the stereo Mix output while muting the other Mix signals. The PFL/AFL selector has no effect while SIP is active.
  • SOLO ON: illuminates whenever a console solo is active.
Solo in Place affects the stereo Mix output

If the ASP4816-SE stereo Mix output is being recorded, the use of SIP will be captured in that recording. Do not use SIP while recording or printing the stereo Mix unless this behaviour is intended.

Stereo VCA bus compressor​

ASP4816-SE stereo VCA bus compressor controls

The onboard stereo bus compressor is positioned after the Mix Insert and before the Master Fader.

Gain-reduction meter12 segments
Threshold−20 to +20 dBu
Attack0.1, 0.3, 1, 3, 10, 30 ms

Release0.1, 0.3, 0.6, 1.2, 2.4 s, Auto
INInserts the compressor into the stereo Mix path

For stronger peak control, select a higher ratio such as 10:1 and set the threshold so that compression acts primarily on the required peaks. Use the gain-reduction meter to monitor the amount of processing being applied.
